Effect

Generation I

Double-Edge inflicts damage and the user receives recoil damage equal to 25% of the damage done to the target.

If the user of Double-Edge attacks first and makes itself faint due to recoil damage, the target will not attack or be subjected to recurrent damage during that round.

Self-inflicted recoil damage from Double-Edge from the previous turn can be countered if the target does not make a move on the following turn. If Double-Edge breaks a substitute, the user will take no recoil damage.

Double-Edge has a base power of 100 in this generation.

In Pokémon Stadium, no recoil damage is taken if Double-Edge knocks out a target.

Generation II

Double-Edge's base power is increased to 120. The user will take recoil damage even if a substitute breaks.

Aggron rushes at the opponent and tackles it with great force. While charging, it leaves behind a silver or gold trail, or Aggron's body turns gold and it charges at the opponent. As it charges, its body returns to normal color and it becomes surrounded in a white aura. It then slams into the opponent with great force.
